Northrop Grumman interview questions

I applied online November 17, an HR recruiter contacted me on Novemeber 19 to try and set up an interview. They originally wanted to schedule an interview the following week but due to the Thanksgiving holiday, I pushed it back to December 2. Interview was a panel interview with the hiring manager, a senior level employee in the same group and the production manager. It was very laid back and pleasant. I received a call from the recruiter the following week to inquire about the amount of money I was looking for. She gave me a range of what I could expect and also inquired if I would accept a signing bonus. She called me December 17 and requested that I let her know of my decision by December 21 because their site was about to go on Holiday shutdown. I didn't receive the offer until December 21 and I never heard from the recruiter again. I emailed her and called her multiple times because I had a few questions about the benefits. Turns out she left the company and someone new took over my profile. We finally resolved everything on January 8, 2016 and I start on January 25.
